I am using the NetworkActivityIndicator to show that my App is doing some work. When I run the app in the simulator, it shows the way I want - basically spinning the entire time until the selected tab loads the data from the server - but when I put the app onto my phone, I only get a split-second of the spinner before it disappears. Usually only spins right before the view appears on the screen.
Ideas?
EDIT: The problem might have to do with the fact I am using a TabBar... In the simulator the ActivityIndicator will spin on Screen/Tab 1 while Screen/Tab 2 is loading. On the phone, I only see the ActivityIndicator for a split second after Screen 2 finally appears.
-(void)viewDidLoad {
// call to spinTheSpinner
[NSThread detachNewThreadSelector:@selector(spinTheSpinner) toTarget:self withObject:nil];
// method to Get the Data from the Server
[self getDataFromServer];
}
-(void)spinTheSpinner {
NSLog(@"Spin The Spinner");
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[self performSelectorOnMainThread:@selector(doneSpinning) withObject:nil waitUntilDone:YES];
[pool release];
}
-(void)doneSpinning {
NSLog(@"done spinning");
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
-(void)getDataFromServer {
// does a bunch of stuff to retrieve and display data
}
